The "recovering database" may take a few minutes to complete.
Check the errors log file again for any newer messages after the recovery.

For the crash, or if till not starting up, try to get a core file and stack trace:
https://www.port389.org/docs/389ds/FAQ/faq.html#debugging-crashes
https://www.port389.org/docs/389ds/FAaQ/faq.html#debug-startup-crashes

Since the system is running with RHEL, a Red Hat ticket should be opened, with valid credentials, at
https://access.redhat.com/solution-engine/#/productSelector/?product=Red%20Hat%20Directory%20Server

Extra note: the current version is with RHEL-7.7 / 389-ds-base-1.3.9.1-10.el7.x86_64
( includes many fixes since 389-ds-base-1.3.7.5-24.el7_5 )

Thanks,
M.
